this ended up being a torture test for my printer, after countless failures i was able to get a complete print. it kept skipping steps until i lowered my stepper motor current and decreased the acceleration. printed nicely.

Thanks Andychn!
the secret is to try and try again until you get it right :)
That's what Rapid Prototyping is for right?
My first few prototypes did not even fit properly. For designers who want to design male/female threads, model a CAD design of the male and female thread on a small size first and print them out. If it fits, use the design on the actual final design and print it out. Saves time and material. I learnt it the hard way hehe ;)
